IMPROVEMENT IN THE MANUFACTURE OF GLASSWARE.

Specification forming part of Letters Patent No. 163,787, dated May 25,1875; application filed April 19, 1875.

' of this specification, in which, like letters indicatin g like parts-Figure l is a view in perspective of a glass vdish having claw-shapedfeet pressed thereon.

Fig. 2 is a top or plan view of one form of mold in which such articleis made. Fig. 3 is a sectional view thereof in the line x w, Fig. 2.Fig. 4 is an inverted or bottom view thereof, and Fig. 5 is a plansectional view as formed by a horizontal plane passing through the moldon a level with the upper face of the movable side sections.

In a separate application filed by myself and August Sperber, February27, 1875, we described and claimed one construction of mold suitable formaking a bowled article of glassware with feet pressed thereon at thesame operation, such feet having an inward or re-entrant cunve on theirouter sides or edges, or being, as I now for convenience designate them,claw-shaped.

,My present improvement relates to the article thus made, that being myown invention, and to another construction of mold for making the same.

The mold shown in the drawing consists of an unjointed part, B, for thepressing of the bowl therein, and which part may be either made as apart of, aixed to, or arranged on a base part, B. This base part B has aneck, b, in the outer periphery of which are the leg or foot cavities a,which latter communicate with the bowl-cavity above, and below'the neckb the base B flares outwardly, as atb', so as to form a bottom to thefootcavities a, and also a base for the hinged sections D.

These hinged sections D encompass the neck b; but such parts of them ascome opposite to the foot-cavities a are so formed, as at d, as to closeup the foot-cavities a on the outer sides or edges thereof, and' thusmake the cavities complete for the pressing of the feet a therein; butalso these faces d are shaped so as, when in position for pressing, toform each a re-entrant part, extending inwardly beyond the extremetip ofthe foot a', or end of the cavity a, as illustrated in Fig. 3. Thus, inthe foot a', as pressed therein, I get on the outer side or edge of itan inward curve.

The sections D are hinged together, as shown in Fig. 5, so they may bebrought up and closed onto the neck b while the pressing is being done,and also so that, in order that the article, when pressed, may be removed from the mold, they may be thrown back until the parts d arebeyond the tips of the feet a.

To this end two of the sections should receive iirst an outward motion,in which they will be guided by stems c affixed thereto, and playing inslots e in the base-ange b', and then all may receive a backward motionby the stems c c c passing along the slots e; but other modes of givingthese sections D an 0utward-or backward horizontal motion may beemployed; nor is it essential that they should be hinged one to another.

The mode of pressing will be readily understood by those skilled in theart.

This construction of mold gives a iinless body or bowl, A, the only iinproduced being along the joint formed by the re-entrant part d and theedges of the cavity a; and such fin, by a bead or otherwise, may be soperfectly concealed as not to be objectionable. In this manner I producea bowl, A, having a Iinless or seamless body, and pressed claw-shapedfeet made thereon at the same time and in the same operation.

The same mode of manufacture may be employed in the production of footedarticles of hollow glassware generally.

I claim as my invention- 1. As a new article ,of manufacture, aprcssediinless or seamless hollow article of glassware having claw-feet pressedthereon, substantially as set forth.

2. The combination of hollow mold B, hav- In testimony whereof I havehereunto set ing a cavity of any desired form for pressing my hand.' thebody of the article to be made, a base, b, in which are thefoot-cavities a, and movable sections D, having re-entrant faces d, .andWitnesses: moving in horizontal planes7 substantially as J AMES M.CHRISTY, set forth.
